Ekman's model proposes a small set of basic emotions that are recognized across cultures and expressed through distinct, universal signals: anger, disgust, fear, happiness, sadness, and surprise. Each is treated as a discrete affective state with characteristic antecedents and appraisals, rather than a point on a continuous mood dimension.
This taxonomy is a compact, widely used scheme for emotion and sentiment annotation. Tag spans where the subject expresses one of the six emotions in their own words and assign the matching label (optionally with an intensity). Emotion words that appear only in the interviewer's question are not coded, and neutral or purely informational speech is left untagged.
